Oracle Chinese Character occupies byte length, oracle Chinese Character byte 1. When investigating an oracle database problem today, we found that one Chinese Character occupies 2 bytes in 11G and 3 in 10g, as a result, the data in the 11g Database is always wrong when it is imported into the 10g Database. At the beginning, it was thought that the version of the 11g Database is different from that of the 10
